What is the process called when minerals replace organic material in dead organisms, forming a stone-like replica?

• Adaptation

• Metamorphosis

• Petrification

• Crystallization

Scientists have collected millions of fossils of different organisms, and have developed a timeline of life on Earth. What do we call this?

• Mutation

• Natural Selection

• The theory of evolution

• Fossil Record

The fossil record is important for understanding evolution because it provides:

• Direct evidence of genetic drift

• Evidence of past organisms that have gone extinct

• A record of all mutations that have occurred

• Proof of natural selection in current species

This diagram of the fossil record represents changes in mollusks over millions of years. How can the pattern of change in the fossil record best be explained?

• There was a period of sudden change followed by stasis.

• There was a period of stasis followed by rapid decline.

• There was a long period of sudden change.

• There was no period of change.

The fossil record provides evidence that 

• Fossils cannot be dated.

• All species were formed during Earth’s formation and have changed little since then.

• The fossilized species have no connection to today’s species.

• Older species gave rise to more-recent species.
